STRUCTURE FOR SUBMARINE SEWERS.

SPECIFICATION forming part; of Letters Patent No. 326,544, dated September 22, 1885.

Application filed April 30, 1885. (No model.)

To all whom it may concern.-

Be it known that I, HENRY CASE, a citizen of the United States of North America, and a resident of Brooklyn, county of Kings, State of New York, haveinvented a new and useful Improvement in Structures for Submarine Sewers, of which the following is a specification.

The object of this invention is to provide a structure for submarine sewers, designed for conveying the sewage of cities and towns to any desired distance out into the ocean, lakes, or rivers.

The invention consists of the combination, with the sewer pipe or pipes, of a system or series ofsupporting and bracing piles, and suitable braces and fastenings of novel design and arrangement, whereby a cheap, durable, and strong structure is formed, which is calculated to withstand the action of winds and waves,all of which will be hereinafter set forth.

Reference is to behad to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents an end elevation of the structure. Fig. 2 is an enlarged plan of the top of a brace-pile. Fig. 3 represents enlarged views of a novel form of link used in the structure. Fig. 4 is a partial side elevation showing a valve in the end of the sewer pipe. Fig. 5 is a partial end elevation of the style ofstructure designed for supporting more than one line of sewer-pipes. Fig. 6 is a side view of a portion of the same. Fig. 7 is a plan of the portion of the structure supporting more than one pipe.

In the drawings,A represents a central supporting-pile, preferably hollow, and provided with a fixed terminal shoe, a, and a movable shoe, b,- and B B represent brace-piles provided with like shoes and fixed at suitable distances on either side of the pile A. These piles, (one or more central and two brace pi1es,) with thebrace-rods,&c.,hereinafter described, form one supporting-section of the structure, and these sections are designed to be multiplied as required, fixed in line, say, ten to fifteen feet apart, to extend as far out from shore as it may be desired to conduct the sew- The piles A B, with their shoes, are similar to those for which Letters Patent of the United States were granted to me August 15, 1882, N 0. 262,569, and hence require no detailed description herein.

An important feature of the structure is a bearer, 0, whose sleeve 0 is designed to fit over and upon the head of a pile, A, and form the cap thereof,and to be rigidly secured thereto by bolts c.c. This bearer, presenting its concave face upward, is designed as a rest for the sewer-pipe, and the pipe is held firmly in position by a. strap, (1, which is bent over the top of the pipe, and has its screw-threaded ends passed down through opposite bosses, f, on the said bearer or cap 0, and nuts 9 9, turned on these ends, draw and hold saidstrap firmly down. In this manner the sewer-pipes (the various sections or lengths thereof being coupled together in suitable manner, as indicated at 0 Fig. 6) are all securedto their supporting-piles when but one line of pipes is set up.

In order to brace the pipes against the action of the waves or tide, a double turn of a chain, E, is made about the sewer-pipe near each supporting-pile, as shown in Figs. 1, 5, and 6, and in the terminal links of said chain are hooked brace-rods h h, whose other ends are secured in or to swinging links F, which are held by bolts m, passing transversely through the tops of the brace-piles B B.

Iron sleeves m inclose the bolts m within the piles B B, to prevent the collapsing of the sides-of the piles when the bolt-nuts m are turned tightly down. Both bolt m and sleeve m then pass through the lower eye of a link,

F, which swings on the sleeve, while in the upper eye of the said link the lower end of a brace-rod, h, is engaged.

Thus it will be seen that the pile-shoes, the bearer, chain, strap, and brace-rods combine to make each section capable of resisting a.

powerful opposing force.

In the mouth of the last or extreme section of pipe aswinging valve, G,is preferably fixed, as shown in Fig. 4, that will close against inflowing water,and will open to the outflowing sewage; and, when desirablafithe sewer-pipes may be ventilated in the ordinary manner by upright pipes.

When two or morejilinesfiof sewer-pipes are to be laid,each supporting-section is composed of two or more supporting-piles, A, devoid of the bearers or caps O, andinstcad of said caps a bearer or bearers, H, as shown in Figs. 5,6, and 7, is or are used for supporting the pipes. The bearer H is essentially a rectangular box or frame with wrough't-iron top and bottom' and cast-iron sides 0 o 0 respectively, and having semicircular depressions (con cavities) 19 for reception of the pipes, and with ends formed to fit against the piles, as shown at p. 7

The bearer is secured to the pilesAby bolts q, passing down through it into brackets s, which are firmly bolted on said piles, as shown in Fig. 5, and by tie rod or rods t, passed longitudinally through the bottom of the cradle and through the piles A; and when two or more bearers Hare required in a section they are secured endto end by suitable fasteniugs, s, as shown. In this casethe straps d, which pass over the sewer-pipes, are passed down through the bottom of the bearer and there secured, as indicated. In this case, too, only the outside lines of pipes are held by chains and brace-rods, as indicated in Fig. 5, and the outer ends of the brace-rods may be simply securedby eyebolts o,Fig..5, to the brace-piles.

This supporting structure can be used for carrying pipes or tubes for conveying oil, water, gas, telegraph-wires, or for conveying packages, &c.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A supporting structure for submarine sewers, constructed in sections, substantially as herein shown and described, each section containing one or more supporting-piles, A, two or more brace-piles, B, all provided with suitable shoes, apile-bearer, chain E, links F, attached to the brace-piles, strap d, and bracerods h, connecting, the links and chain, all arranged and operating substantially as set forth.

2. 111 a structure for submarine pipes, the combination, with supporting-piles A, bracepiles B, bearers, chain E, links F, bolts m, straps d, and brace-rods h, of thepipes D, all arranged substantially as herein shown and described.

3. In a structure for supporting submarine pipes, as a means for holding the pipes to the supporting-piles, the combination, with bearers secured to the said piles, of straps, as d, all arranged substantially as herein shown and described. I

4. In a structure for supporting submarine pipes, the combination, with the pi pe-supporting piles. of concave bearers for receiving the pipes, substantially as herein shown and described.

In testimony that I claim the foregoing as my iny'entiou I have signed my name,in pres ence of two witnesses, this 23d day of April,
